7 Claims.

The invention aims to provide a new and improved article in which a tube iseemployed to contain a paste or liquid and to extrude same as required to an applicator carried by said tube, the tube acting as a handle for operating the applicator and enabling efiective use thereof to apply the extruded paste or liquid to any desired surface.

In carrying out the above end, a further object is to provide the device with two applicator surfaces which converge outwardly from one end of the tube and join each other along a ridge line, giving greater applicator area, enabling more convenient use of the device, and providing a rather sharp corner or ridge which may be used to apply the extruded paste or liquid in angular places, for example, those existingbetween the welts and uppers of shoes.

A still further object is to provide a device'of the class described which is normally sealed in a novel way yet will permit extrusion simply by pressing inwardly upon the Walls of the tube.

With the foregoing and minor objects in view, the invention reside in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawings.

Fig. 1 is a vertical sectional view partly in elevation showing one form of the invention with the discharge openings in the tubular container sealed. I

Fig. 2 is a view similar to Fig. 1 but showing the manner in which the tube contents can be extruded.

Fig. 3 is an end elevation looking down on Fig. 1.

Fig. 4 is a view similar to Fig. 3 with the applicator pad removed.

Fig. 5 is a side elevation partly in section showing a different form of construction.

' Fig. 6 is an end elevation looking down on Fig. 5.

Fig. '7 is a fragmentary elevation partly in section showing a still further form of construction, the discharge opening being sealed.

Fig. 8 is a View similar to Fig. 7 but illustrating the manner in which the tube contents may be extruded.

Fig. 9 is an end elevation looking down on Fig. 7.

Fig. 10 is a detail sectional view through the elastic disk of Figs. '7, 8 and 9 showing the manner in which it is cut to provide the discharge opening and sealing tongue of said figures.

In Figs, 1 to 4, I0 denotes a tube of such nature that opposite sides thereof may be readily pressed toward each other to extrude the tube contents l I. This tube is provided with an end wall consisting of two halves l2 and 12 which converge outwardly and join each other along a ridge line l3, each half being formed with an opening l4 spaced from said ridge line. An applicator pad is cemented or otherwise suitablysecured against the outer side of the end wall l2, l2, said ap-, plicator pad being preferably formed from sponge rubber and consisting of two outwardly converging halves l5 and I5 joined along a ridge line l6 which rests on the ridge line ,[3 of the tube end wall. This ridge portion of the applicator is formed with a small opening ll. ,The restricted portion of the applicator within the dotted line I8 (Fig. 3) is free from connection with the tube end wall, said portion extending over the ridge 13 of said end wall and preferably to the lower edges of the openings I 4. Within ,this restricted portion of the applicator, the

opening I! is located. a

The above mentioned restricted portion of the applicator pad is denoted at l9 audit will be observed that it normally liestig'htly against the end wall I2, 12' of thetube ID to forma seal between the openings !4 and the opening I]. However, when the sides of the tube are pressed inwardly to extrude some of the contents! 1 said contents must outwardly bulge (Fig. 2) the portion IS in order to pas through the opening I4, on to the opening l1, and through the latter. When pressure on the side walls of the tube is discontinued, extrusion stops and when the applicator halves l5 and I5 are used to apply the extruded substance, the pressure necessarily again forces the outwardly bulged applicator portions into tight sealing contact with the tube end wall.

By providing the applicator with two converging halves and a corner or ridge connecting them, the efiective surface of the applicator is increased, the entire device may be held in a more convenient position while using same, and a rather sharp corner is provided to reach into angular places where the extruded substance is to be applied, for example, in the angles between the welts and uppers of shoes.

In Figs. 5 and 6, th tube 10 is provided with an end wall l2 of the same construction as the end. wall above described,,the two halves of said end wall being formed with openings M cOrresponding to the opening 14 while the ridge of said end wall is provided with an opening'20. The applicator pad l5 may be identical with the pad above described, but it is secured throughout its inner area to the end wall ll and is provided with self-closing slits I! in the portions thereof which extend across the openings I l and 20. The device has the same advantages as those above set forth. It will be obvious that the slits Il are normally closed and thus, form seals, yet that when the sides of the tube'are 'mwardly pressed, the tube contents will be extruded through said slits, due to the stretch of the sponge rubber or the like permitting said slits to open somewhat.

In Figs. 7 to 9, the tube M is provided with an end wall l2 shaped as above described, but preferably of considerably less pitch, the ridge of said end wall |2 being formed with a comparatively large opening [4 A disk 2| of rubber or the like is cemented against the lower sides of the converging halves of the end wall [2 and is provided in its ridge-portion with an opening 22 under the opening M A tongue 23 is provided to normally close the opening 22, one end of said tongue being integrally joined to the disk 2| at one end of the opening 22. The tongue 23 extends obliquely through this opening 22 to the exterior of the disk 2|. and has its free end positioned within the opening I4 said free end resting upon the corner 24 between the upper side of the disk 2| and the end wall of the open,- ing 22 subjacent to said free end of said tongue. The opening 22 and tongue 23 may be simultaneously formedby cutting a U-shaped slit in the disk 2| as shown in Fig. 9, the free end of the tongue and the contiguous end of the opening being inclined sothat the'corner 24 will be provided to underlie and contact with said free end of the tongue to normally seal the tube.

When the sides of the tube are pressed toward each other, the tube contents will beextruded, causing the tongue 23 to outwardly yield until the pressure is stopped, whereupon the resiliency of said tongue again closes it. The extruded material may be applied to any desired surface by using either half of the end wall l2 as an applicator.

From the foregoing taken in connection with the accompanying drawings, it will be seen that novel and advantageous provision has been made for carrying out the objects of the invention. While preferred details have been disclosed, minor variations may of course be made within the scope of the invention as claimed.
